BARBED FENCING-STRIP.

BPECIFICATION forming part of Letters Patent No. 305,283,!latedSeptember 16, 1884.

Application filed December 17, 1881. (No model.)

To all whom at may concern:

Be it known that 1, WILLIAM E. BROOK, of New York city, in the countyand State of New Yorlg'have invented certain new and useful Improvementsin Barbed-lifetal-Strip Fencing; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, forming a part of thisspecification, in which Figure 1 represents a section of my im provedbarbed fencing complete. Fig. 2 represents a side view of a section ofthe plain metallicstrip material used in the manufacture of the barbedfencing represented in Fig. 1. Fig. 3 represents a side View of thesecond and barbed metallic strip used in the manufacture of the barbedfencing represented in Fig. 1.'

Fig. 4 represents a side view of the barbed fencing after it has beencompleted, ready for the galvanizing and twisting operations, as will bedescribed more fully hereinafter. Fig. 5 represents, upon an enlargedscale, a section on line a b, Fig. 4, looking in the direction of arrow1 of same figure; and Fig. 6 represents. upon an enlarged scale,asection on line 0 (1, Fig. 4, looking in the direction of arrow 2 ofsame figure.

To enable those skilledin the art to which my invention belongs to makeand use the same, I will proceed to describe it more indetail.

1n the drawings, the part A represents a section of a. plain strip ofthin metal, which forms the outer coating of the barbed strip 13, andwhich parts A and B are combined together in the manufacture of mysaidimproved barbed fencing by bending or folding up the edges 0 G ofstrip A, so as to clasp and hold the strip B, as fully shownin Figs. 1,4:, 5, and 6 of the drawings, the edges 0 O lapping up and foldingagainst the strip B, so as to cover its bottom edge, I), as well as itssides up to the base of the barbs E, which barbs E may be cut so as toform a continuous series, as shown on the right-hand end of thedrawings, Figs. 1 and 4; or they may be cut so as to be separated somedistance apart, as shown at the left-hand end of the drawings of thesame figures. After the strips A and B have been united in one, as shownin Fig. 4, it is run through a. bath of molten zinc and galvanized, bywhich operation all the parts exposed to the atmosphere are covered,while at the same time the edges 0 O of the folded piece A are securelyunited to the sides of the strip L, after which galvanizing operationthe strip is twisted so as to cause the barbs to stand in differentdirections, as indicated in Fig. l of the drawings, thereby producing astrong, durable, and effective barbed fencing. If preferred, thegalvanizing process may be performed after the fencing has been twistedinstead of before.

In my application of even (late herewith, serially numbered 48,109, Ihave shown, described, and claimed a barbedstrip fencing consisting of ametal strip folded centrally upon flat metal barbs and spirally twisted.Such construction, therefore, is not included in this application.

Having described my improvements in barbed-metalstrip fencing, what Iclaim therein as new and of my invention, and desire to secure byLetters Patent, is-

A barbed fencing comprising a thin metal strip having a singlelongitudinal fold and a barbed strip inserted in said fold, the twoparts being twisted together, substantially as described.
